Paper Swarm (Su): Your scrollblades can disassemble themselves upon striking an enemy’s armor, creeping into the chinks and striking the enemy from beneath its protections. As a free action when making an attack with a scrollblade, you may spend 1 point from your arcane pool. If you do, treat your attack as a touch attack. The weapon used to make this attack is destroyed whether or not the attack succeeds. You must be a wizard of the paper school to select this discovery.
